I am 25, male, sedentary lifestyle, live in UK. My diet is mostly protein and fats, less than 100g carbs a day. I decided to get into healthier lifestyle and wanted to start running, but was met with feeling dizzy, chest pain and pressure, headache and weakness, shortness of breath.
Hence, I decided to switch to walking but 10 minutes in slow pace, I get same symptoms. Are those cardiac in origin or me being so out of shape? I have been checked a year ago by a cardiologist, who did resting and stress ECG, along with echocardiogram. I was told my pulse went to 186 bpm and it is too high for the activity level. Otherwise, all was okay.
I then had another echocardiogram, this time in ER when I had my blood pressure rise to 150/100, feel sweaty and unwell. I was told it is a panic attack, and that my anxiety and depression needs to be controlled. I then went on to live sedentary lifestyle, and those symptoms cropped up after deciding to exercise again.
My family has a history of high blood pressure, a grandmother had a pacemaker at 69 years old. My mother has hypertension, controlled by medicine. My father is fine at age 55. I had a lot of ECGs over the past year due to panic/anxiety attacks, it felt like my heart is going to explode. They were always normal, they never registered cardiac enzymes.
I would like to ensure that my heart did not get diseased in the last 6 months doing this low car diet. What are the tests to ask for? I would like to know that this is not cardiac origin. Every doctor in ER multiple times said it is not cardiac and that I need to deal with my anxiety somehow.
